To all whom it may concern:

Be it known that I,- HENRY Smonns, a citizen of the United States, residingat Longbeach, in the, county of Los Angeles and State of California, have invented certain new and useful Im' rovements in Acetylene- Controllers; and I. do deto be a full, clear, and ex: act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Gas Generators an his invention relates to acetylene-gas generators and controllers; and one of the principal objects of the same is to provide simple, reliable, and efficient means for automatically feeding carbid to the v gulatin the feeding of the carbid by the actlon of t e gasometer-bell in the gasometer. V

This and other;objects are attained by means of the construction illustrated in the accompanying drawings, in which- Figure 1 is a side elevation and partial section of a generator and gasometer made in accordance with my invention. Fig. 2 is an.

enlarged sectional view of the carbid-feed valve, and Fig. 3 is a detail view and partial section of the mechanism for operating the carbid-feed valves.

Referring to the drawings for a more particular description of my invention, the numeral 1 designates the generator-tank, which is provided with a conical bottom 2, having a discharge outletepipe 3 leading from the lower end thereof out through the wall 4 and provided with a valve 5, adapted to be actuated by automatic means. for discharging the residuum 'or spent carbid at certain intervals-dependent upon the condition of gaspressure in the. gasometer, as will presentlyappear. A partition 6 is formed near the upper end of the generator, and a gas-outlet c amber 7, having a closed upper end, extends into the' partition 6. Dependin the partition 6 is a water-inlet pipe 8, ii its lower end perforated,

from aving as at 9. Above the partition 6 is a float-valve chamber 10. A

water-supply inlet-pipe passes through the valve 12, actuated y means of a float compnsm a ball 13, an arm 14, extending the be] to a yoke 15 connected tothe valvestem 16 to operate the same by means ofthe chamber 1.

generator from water-level in the chamber 10 to discharge water through the pipe 17 into the chamber 10 and through the pipe 8 into the generator- Owing rations 9 in the pipe ,8, water will be maintained in said chamber 1 at a certain predetermined height, and at .the same time water in the chamber 10 will also reach a certain level. An overflow or surge chamber or compartment 18, provided with {an outletpipe 19, is in direct communication with the generator-tank at a point 20, the purpose of the said surge-cham er being to prevent an overcharge of water under certain conditions.- A

as-outlet. pipe 21, having its inlet end 22 wit the outlet- .chamber 7 above the water-line, leads downward and out of the generator to a cleaning device, presently to be described.

' The carbid-feeding device, comprising a chamber 23, having and lower end, is supported upon a hopper or neck 24, which extends through the waterchamber 10 and is open at its lower end directly into the generator-chamber 1. This ho per 24 has secured to its upper end a carbid -chamber 23 by means of suitable flanged clamps 25. Within the chamber 23 is a cap,

26, c osedat its upper end and open at its lower end, as shown, said cap being su ported from within the chamber 23 by suitable means, mounted to slide within the ca 26 at its "upper end, while its lower end is adapted to slide within the tubular lower end 29 of the a frusto-conical upper as by arms 27. A valve 28 is to the size of the perfo- .65 within the generator chamber 23. Connected to the lower end of the valve 28 is a stop-valve O, the upper end of which is frusto-conical, as shown, and said stop-valve 30 is connected to the valve 28 by a rod 31.. Said valves 28 and 30 thus operate simultaneously, as will be hereinafter described. Extending downward through the sto -valve 30 is a stem 32, supported at its on upon a lever 33, pivoted at 34 within an extension 35, formed on the hopper 24. on the outer end of the lever 33 a roller 36 is journaled, said roller adapted to travel upon a cam-wheel 37, fixed to a shaft 38, journaled in a frame 39. The lever 33 has a handle 40, by which it the be operated by hand, if desired, Mounte in the frame 39 'is'a drum 41, around which a cord orcable 42 is passed, andcoiinected to the lower end of said cable-is a weight 43, said weight being disposed immediately in front of a vertical scale 44, containing certain marks to indicate the condition of the generator, as will hereinafter a pear. On the end of the drum 41 is a cran 45, by means of whichthe weight may be'raised. A gear-wheel 46 is mounted with a depending brought into contact with the brake-wheel.

on the crank-shaft and is in mesh with a gear 47 on the shaft 38 of the cam-wheel 37, While the gear 47 is in mesh'with a ear 48 on .a shaft 49, carrying a brakeeel 50. A brake lever 51,'pivoted at 52 and provided with an adjustable weight 53 is provided arm 54,'adapted to be 50 to cut off the feed of carbid to the generator when the gasometer-bell ascends beyond a certain point and :to release the brakewheel upon the descent of the gasometerbell, ,aswill be understood. A chain 55 is.

attached at one end to the lever 51 and at the opposite end to the top of. the gasometerbell. v The gasometer comprises a condensingchamber 56, se arated om the gas-chamber 57 by means 0 a partition 58; The gasometer-bell is fitted to operate within a water- 'acket in the usual manner. A gas-filter 60, avin its lower end discharging near the bottom 0 the condenser-chamber 56 and its upabove the water-level in.

per end extendin passing through the partithe gasometer an tion 58, is partially filled with suitable filterinto the by means of a wire gauze cap 62. The gaeipassing. through the p pe 21 is led into the ter 60 and dischar es into a flaring outlet-nozzle 63 within ing material 61, held therein the lter 60, the gas then'rising through the or cover 69, connected to a' yoke and hel in placfilllilyi means of 'a lever 71, pivoted at 72, and a top of the carbid-chamber 23. The lever '71 78, bolted' to a keeper 74 at'the is provided with a toe 7 5, adapted to enga e a pivot-hook 76 to hold the cap or cover 9- in place.

A'string or cord 77is conneeted to one end of the lever 71, and the op osite end of said cord is connected to a weig ted lever -7 8, pivoted upon a bracket 79 'andprovided with a projection 80, said pro to come into contact with t e wheel. 37to .stop the feeding of carbid at a: i

'ection adapted ace of the -cam-- 59 downand theminor details of construction may be from the chamber 23 or when said chamber is being filled with comminuted carbid. The valve 5 is provided with a stem 81, to which is connected alever 82, and pivoted to the lever 82 is a weighted arm 83, connected at one end to a rod 84, u on the u per end of which is a roller 85, adapted to e actuated by the cam-wheel 37 to open the valve 5 and discharge the spent contents of the generator at a time when the supply of gasin the gas ometer is low, as will be understood.

. A blow-oil pipe 0,, provided with an outletpipe b, located in line with'the condenserchamber, is provided as a means'of preventg the accumulation of an excess of gas in the condenser. f

time when thevcap orcover 69 is removed 65 The operation of my invention may be deseribed as follows: 'Water having been fed to f theenerator-chamb'er andto the chamber 10 t ough the valve 12- and water having 35 been fed to the gasometer through the I i'pe 64 and the weight 43 having been 'woun up, the service-pipes in'the building' are now opened to a low the air to esca e from the ;gasometer before the feeding o the carbid commences. The handle 40 will now be oj erated to feed carbid to'the gen era'toran to the cleaner, up-through 'the cleaner-to the commence the generation of gas, The gas generated passes through the outlet-pipe to gasometer-bell, and thence down the filterpipe to the en the gasometer-bell ascen lever which controls the" feeding mechanism as will be understood. The valve28 is raise bythe mechanism until the stop-valve 30 cccupies'. a position in the lower end 29 of the carbid-chamber, the carbid then being fed ;downward u on the 11 per end of said stopvalve. As t e valve ops the carbid isdeposited in the generator through the hop 'er outlet or supply pipes."

it 'actuates the I24, as will be understood, the valve 28 t en remaining in its lowermost osition and stopping the feeding of carbi until it is again 1 raised by the mechanism actuated byfthe ;cam-wheel 37 to again feedthe carbid.

Various changes in the form, proportion,

resorted to without departing from the prin-" :ciple 'or sacrificing any of the advantages of this invention.' 1 H g Having thus described my ihvention, what .I claim as new, and desire to secure by Letters Patent; is
